Troubleshooting 12/24 volt Danfoss BD compressors.
(snipped)
Hi, Richard, and thanks for the note.
I've been all through the Danfoss literature, and many sources of what you
posted.
At this point, I'm reasonably sure that I have a leak in the "yellow" line
at the connection point, as the brass (copper?) part has what appears to be
some oil on it. The compressor runs, but no cooling happens - the lines to
and from the keel cooler as well as the compressor temperature are ambient.
I have a friend with a vacuum pump and the necessary adapter (he sez) to
attach a 134a can to my gauge set. However, I'm killing myself/going blind
trying to figure out which of the connection points (as they're not labeled
as such in the Danfoss literature, nearly everything related to a Bd50F and
101N0210 controller of which I believe I've read or looked at for
diagrammatic help) to which to connect my gauges/supply line.
Early on, we had a slight overcharge condition, likely due to the diligence
of the installation (SALT, my vendor, told me that the systems/lines were
slightly overcharged in production on the presumption that some would be
lost during connection make-ups). SALT suggested I open the top to the line
which is T'd into that yellow line, and cautiously vent a very little at a
time until my line from the freezer no longer had ice on it.
I did so, and all was well for some years, until just lately. New O-rings
are on the way from them, but I've discovered a small plastic bag which I
thought I'd remembered being attached to the compressor; it has three of
what I presume are the same O-rings in it. Therefore, one way or the other,
once I buy a can/dispenser setup, I think I should be ready to proceed to
replace that O-ring, evacuate, and recharge.
So, as I look at a keel-cooled Bd50F, 101n0210 controller with SSC attached,
setup, with the factory controller on the left, there's a heat-shrunk seal
on the top of the only other fitting I can see (there may be another in the
rear; I've not taken off my protective box - plywood with umpteen holes in
the top, and along the bottom sides, with the front, not likely to have any
contact with anything, open - in the engine room, yet) on the left top.
There's what I presume to be a capillary tube on the rear, which I also
presume will have a connection to a line, but I can't see it, as above (if
needed, I'll excavate the engine room to remove the box). It may have a
connection point, too.
So, can you tell me where to connect the high and low pressure lines, and
where to connect the supply (new 134a), to check it, as well as where to
connect the vacuum line before recharging? As well, should I be concerned
about the few drops of apparent oil loss? Their info strongly cautions
against charging with anything other than unadulterated 134a...
Also, my SSC has a trouble icon. Does this function as the LED for
blink-code information, would you know?
Thanks for checking in!
